Expansion
Options
The mainboard comes with the following expansion options:
•
Three 32-bit PCI slots
•
One AGP slot (supports 1.5V AGP card only)
•
Two IDE connectors which support four IDE channels and
a floppy disk drive interface
The L4S8M supports Ultra DMA bus mastering with transfer
rates of 33/66/100/133 MB/sec.
USB
The USB 2.0 Controller is compliant with Universal Serial Bus
Specification Revision 2.0.
The USB 2.0 supports data transfer rates up to 480MB/sec for
high-speed devices and specifies a microframe that will be
1/8
th
of a 1msec frame. This allows the USB 2.0 devices to
have small buffers even at high data rates.
The USB 1.1 connectors and other full speed cables can sup-
port the higher speed of USB 2.0 without any changes.
The chipset has the following advanced USB features:
•
Compliant with Enhanced Host Controller Interface
(EHCI) Specification Revision 0.95 and Universal Host
Controller Interface (UHCI) Specification Revision 1.1
•
PCI multi-function device consists of two UHCI Host
Controllers for full/low-speed signaling and one EHCI Host
Controller core for high-speed signaling
•
Supports PCI-Bus Power Management Interface Speci-
fication release 1.1
•
Legacy support for all downstream facing ports
Onboard LAN
(optional)
The RTL8100B(L) is a highly integrated and cost-effective
single-chip Fast Ethernet controller. It is enhanced with an
ACPI (Advanced Configuration Power Interface) management
function for PCI in order to provide efficient power manage-
ment for advanced operating systems with OSPM (Operating
System Directed Power Management)
It provides the mainboard with 10/100Mbps fast Ethernet con-
troller and integrated Ethernet PCI LAN capabilities.
IEEE 1394A Con-
troller Interface
(optional)
•
Fully support provisions of IEEE1394-1995 for High- Per-
formance Serial Bus and the P1394a draft 2.0 standard
•
Provides one compliant cable port at 100Mbits/s,
200Mbits/s, and 400Mbits/s
•
Supports arbitrated short bus reset to improve utilization
of the bus
•
Data interface to link-layer controller provided through
2/4/8 parallel lines at 50Mbits/s
•
Support power-down feature to conserve energy in bat-
tery powered applications
Integrated I/O
The mainboard has a full set of I/O ports and connectors:
•
Two PS/2 ports for mouse and keyboard
•
Two serial port
•
One parallel port
•
Four USB ports
•
One 1394 port (optional)
•
One LAN port (optional)
•
Audio jacks for microphone, line-in and line-out
